B D-SPRING,

To all whomitmay concern: 7

, Be it knownjthat 1, .JosEPH F: HAMM- RICH, a citizen of the UnitedStates, residing atCleveland -in the county of Cuyahoga and State, ofOhio, have inventednew' and useful I'mprovements in Bed-Springs, ofwhich 2 the following is a specification.

This invention relates to; an improved construction of bed bottoms-T thesaid: bottom-including springs for imprevented.

parting a resiliency thereto, but the con struction beingsuch that greatstrength and rigidity is afforded to the parts comprising the same sothat lateral or longitudinal movement of such parts'wi ll be effectivelyIt is also'my purposeto produce a bed bottom in which the use of theordinary coil springs for supportingthe mattress isdispensed with,springs of a novel construction,

, ing employed, the-saidsprings holding the proximately on the line 33of Fig. 1; Fig4=is a longitudinal sectional view apously stated spacedan equal distance from each other and on the slats 7. The side membersof the clips have their upper ends bent embodying great strength andendurance betop; andbottom elements of the construction in proper spacedrelation with each other,

means -which materially reinforce the construction being employed forholding the springsin proper; position and preventing lateral orlongitudinal movement of the parts comprising therconstruction.

It is a still further object ofthe invention to produce a bed bottomwherein the construction is simple, I embodying great strength anddurability,.but which may be cheaply manufactured and marketed.

The foregoing'objects, and others which Will appeartasl the nature ofthe invention is betterunderstood, may be accomplished by a simpleconstruction, combination and operative arrangement of parts asillustrated by the accompanying drawings, in which V igure his aperspective view showing the arrangementof the improvement on abedstead;

I Fig, 6 is a perspective View of one of-the clips.

f In the drawingslike reference characters indicate corresponding partsthroughout.

Referring now to the drawings in detail an ordmary bedstead is indicatedby the numeral 5' and my improved bottom therefor is indicated ingeneral by the numeral 6.

The bottom is preferably wholly con.- structed of metal, each of theseparate elements constituting the same being similarly constructed.This is a distinct advantage in reducing the cost of the construction aswell as rendering the'parts thereof interchangeable.

The base and supports for the bottom, in

the device illustrated by the drawings com prise eight similarly formedmembers, it bemg, of course, tobe understoodthat a less or a greaternumber of these members may be employed if desired. Each ofthe membersisconstructed from a single strip of suitable material, metal preferred,and each.

constitutes a bottom portion inthe nature of a slat/ having its endsgiven a half twist to providethe sides 8, the'said sides of course beingarranged at a right angle with respect to the slats so that the edges ofthe slats are presented upwardly when the device is arranged upon thebedstead and the outer faces of the sides or what may be termed the arms8 are presented to the sides of the rails 9 of the bedstead. The upperends of the arms are bent upon themselves outwardly at a right angleand'from thence downwardly,'thus forming the ends of the tially U-shapedbody, the sides of, which being' properly spaced to contact with theopposite faces of the slats 7 the said clips being secured to thesaid.slats by rivets,-bolts or similar elements 12 passing through both theclips and slats. It will be noted, by reference to the drawings that theclipsare arran ed in alinin series bein as revioutwardly at a. angletherefromf PIG: vldlng ears 13. The ears are arranged prefv.

era bly flush with the upper edges of the slats 7 on whichthe'respective'series of "clips are secured, and arranged over the earsofall of the series of clips 11 are straight bar's: 1 1, the said barsbeing, of course of the desired lengthto be snuglyreceived between theend rails orthe head-and foot-board of the bedstead, and the ends of thebars 14 terminate with the'ends ofthe outer-1 ears on the end slats ofthe. support. Theba rs 14 are securedto the ears by rivets, bolts orthe'like, indicated 'by the numerals 15."

'By reference to the drawings it will be seen th'at siX of thelongitudinal bars 14 are employed,and consequently six clips are sefable resilient material and being substantially Z-shaped; Thelower-horizontal arm 16 of each of'the springs 17 restson the bars-1 1and is secured to the bars and to the ears of the clips-'11 by certainof the-elements-15 which connect the barsto the ears of the'clips. lTheupper arms of each of the springs 17 areindi'catedby the numerals 18 andarearranged-o'nly slightly below theangle ends of the-arms which providethe up 'permembers of the books 10. By-refer'ence to'the drawings itwill be noted that the springs 17 are reversely arranged, that is, theoppositely disposed pairsof springs have their angle portions directedinwardly toward each other. This adds. to the strength of-theconstruction, as such arrangement of the springs, tea/certain extentprovides reinforcements for each other,

i and for the upper portion of the bottom which will now be described.

0n the upper arms 18 ofeachofthe series of springs 17' are securedbars'19, of a similar size'andlength to that of thelower bars 14. Thebars 19 are secured to the arms 18 ofthe springsb-y rivets or the like,and these securing elements which are indicated by, the numerals 20 alsoconnect-to. the up per bars '18 transverse slats 21.1" The flat faces oftheslats 21 are arranged on' th'e'b'arsi 19, so that the edges of thesaid slats 21 are horizontally disposed and are at a rightfansgle withrespectto'the'verticallydis o'sed faces of the, slats 7.; The slats 21hol the ingthe bars 19 against movement in a longitudinal directlon. Thesprings 17 are of a gage to afford the desired resiliency to a mattresswhich is arranged on the slats 21.

The construction, as previously stated, is simple, "Thed'evice may becheaply manufactured and marketed, r j a As previously stated, the -bedbottom is constructed ofmetal, and the'elements constituting the sameembody 1 a natural amount of resiliency.
